thats a real grey area any serious engine upgrades or mods the dealership kinda looks down apon .. I do know for a fact that the dealership sometimes will not work on any engines that have mods done when a warranty is in play ..

maybe someone else may be able to chime in with some info :)

Is your 2007 a Classic body style, or new body style? Mine is a 2006 with the LBZ and the Classic 2007's should be the same and then they went to the LMM for the new body style. I am looking at upgrading my exhaust as well but only going with a 4" cat-back exhaust.
Once my warranty is up I may go for a turbo-back or even a 5" exhaust depending how much I plan to upgrade my diesel.
For now it will just be 4" cat-back exhaust, a cold air intake, and a mild programmer that I can reset to factory settings in-case of needed warranty work.
Too extreme of mods will cause codes to be thrown and then it becomes your problem instead of a warranty issue.

As far as the warranty is concerned, Federal Law protects the consumers right to add aftermarket parts. Gale Banks has a policy of educating dealerships who toss the "warranty voided due to customer mods."

Here is a Gale Banks quote from dieselstop.com
143.166.82.241:(22:38:54) skippy : Gale, I am research modifing my 97, and have conserns about the manufacture's warrenties. I have read what is on your site, but can you give us any tips on how to handle a reluctant dealer?
207.217.174.128:(23:01:37) Gale Banks : Skippy, call us. If you have Banks product, we'll go to bat for you with the dealer. Once they understand federal warranty law, the problems always seem to go away.

Check your RPO code list, it should have the engine code there.

Should be the 8 digit in the vin to identify the engine code. Checkout decodethis for a free vin decoder.
